Python中的十六进制到Base64的转换

2022-01-21 00:00:00 python hex base64

问题描述

我想将 10000000000002ae 等简单的 HEX 字符串转换为 Base64.

I want to convert a simple HEX string such as 10000000000002ae to Base64.

将十六进制字符串转换为字节，然后将字节编码为 base64 表示法，因此该字符串的预期输出:EAAAAAAAAq4=

The hex string is to be converted to bytes, and the bytes are then encoded to base64 notation, so the expected output for that string: EAAAAAAAAq4=

我在网上找到了一个工具:http://tomeko.net/online_tools/hex_to_base64.php?lang=en

I found a tool online: http://tomeko.net/online_tools/hex_to_base64.php?lang=en

但我有一堆 HEX 值需要在脚本中进行转换.

But I have a bunch of HEX values that I need to convert in a script.

解决方案

Python 2 原生支持 HEX 和 base64 编码:

Python 2 has native support for both HEX and base64 encoding:

encoded = HEX_STRING.decode("hex").encode("base64")
